TRACEY Emin's controversial My Bed artwork has sold for £2.2 million at auction in London.

The 1998 work features an unmade bed and a floor littered with empty vodka bottles and cigarette butts.

The work, which was shortlisted for the 1999 Turner Prize, was put up for sale by millionaire art collector Charles Saatchi who bought it for £150,000 in 2000.

It had a guide price of between £800,000 and £1.2m.
